Remarks

An Appointment object maintains information regarding a task for a particular date and time. The start and end of the appointment are stored in the StartDateTime or EndDateTime respectively. To change the start of the appointment without changing the duration, use the OffsetStartTime method.

The AllDayEvent property may be used to indicate that an Appointment occurs on a day or range of days but is not restricted to a particular time within those days. By default, AllDayEvent appointments are rendered differently than non-AllDayEvent appointments. The appearance of all AllDayEvent type appointments can be adjusted by changing the UltraCalendarLook.AllDayEventAppearance. The UltraCalendarLook.AppointmentAppearance can be used to change the appearance for all appointments. The appearance of an appointment can also be controlled on an individual basis by adjusting its Appearance

A new Appointment, can be created by either creating a new instance of an Appointment Constructor(DateTime,DateTime) and adding it to the UltraCalendarInfo.Appointments collection or using the AppointmentsCollection.Add method of the collection. An appointment can also be created using the AppointmentDialog. To display the AppointmentDialog for a new appointment, use the UltraCalendarInfo.DisplayAppointmentDialog. The UltraCalendarInfo.DisplayAppointmentDialog overload may be used to display the appointment information for an existing Appointment.

An Appointment can have a Reminder and AppointmentAction associated with it. When the StartDateTime is reached, the Reminder will be displayed and the Action will be invoked as long as each is enabled.
